Abstract: A dispatch control system includes a data store with records of previously-attended geographical positions of a mobile unit indicating at least a duration of attendance. The dispatch control system is configured to calculate one or more stochastic characteristics for the durations of attendance representative of a variability of the durations of attendance at said past geographical positions, and generate data indicative of an order of attendance for the mobile unit based on travel and estimated durations of attendance. This data is re-ordered and volatility metrics for each set of modified data are determined. The set of volatility metrics is used to modify the data indicative of an order of attendance for the mobile unit. The dispatch control system is configured to transmit to the mobile unit data indicative of geographical positions corresponding to said modified generated data for use in generating routing instructions.

Abstract: Examples are described relating to control of a geographical position of a mobile unit in time. In one example, a dispatch control system is provided. The dispatch control system has a data store with records of previously-attended geographical positions. These records indicate at least a duration of attendance. The dispatch control system is arranged to calculate one or more stochastic characteristics for the durations of attendance based on the records stored in the data store, the one or more measured stochastic characteristics being representative of a variability of the durations of attendance at said past geographical positions. It is also arranged to generate data indicative of an order of attendance for a mobile unit based on travel and estimated durations of attendance. This data is re-ordered and volatility metrics for each set of modified data are determined. The set of volatility metrics is used to modify the data indicative of an order of attendance for a mobile unit.

Abstract: Printer devices occasionally cause electronic documents to be automatically contracted prior to printing, in order to ensure that all of the content to be printed will fit within the dimensions of a page. Where the electronic document includes information having close tolerances, such as information to be printed on an address label or other defined region on a sheet, the automatic contraction may cause the information to be misaligned with respect to the label or other defined region. Automatically expanding the information within the electronic document prior to printing may counter this effect, and increase the likelihood that the information will be printed within the label or other defined region for which it is intended.
